High‐quality wide‐bandgap (WBG) perovskites are essential top‐cell absorbers for perovskite/silicon tandem cells, yet their stability is limited by light‐induced halide phase segregation and defect evolution. Here, we report a molecular riveting strategy that reinforces surface/interface cation‐octahedron coupling...
In mixed-component wide bandgap (WBG) perovskites, the elusive (111) crystal orientation confers enhanced operational stability compared to the conventional (100) orientation, yet typically compromises photovoltaic performance, presenting a critical stability-efficiency trade-off that remains unresolved. We report a th...
Understanding transient kinetic pathways governing the bottom-up synthesis of 2D MoS2 is critical for deterministic growth. Here, utilizing an atomically resolved graphene-based microreactor for in situ heating transmission electron microscopy, we directly visualize the interface relaxation pathways and stacking-regist...
